The Renewal Treadmill Is Running You
Most CFOs don't decide to overpay for health benefits. They just don't decide not to. Every year the carrier sends a renewal, someone reviews it briefly, maybe pushes back 1–2 points, and signs.
That's not a strategy. That's a default.
Defaults compound. According to Inclusively's Budget Reality Check for 2026, employers who do nothing should expect benefit cost growth of 6.5–9.5% annually. Even with plan design tweaks, net increases of 5.8–7.3% remain likely. That may be wildly optimistic for many underwritten groups with poor claims history.
For a 300-life employer spending $4.5 million annually on medical benefits today, that range isn't abstract. It's a number with a lot of zeros behind it.
What 8.5% Trend Looks Like Over Five Years
Inclusively pegs medical trend at 8.5% for the group market. That's the projected rate for employers sitting on fully insured plans and accepting renewals without structural changes. Here's what that does to a 300-life employer starting at $4.5 million in annual spend.
| Year | Passive (8.5%) | Managed (3.5%) | Annual Delta |
|---|---|---|---|
| 1 | $4.88M | $4.66M | $220K |
| 2 | $5.30M | $4.82M | $480K |
| 3 | $5.74M | $4.99M | $750K |
| 4 | $6.23M | $5.17M | $1.06M |
| 5 | $6.76M | $5.35M | $1.41M |
| 5-Year Cumulative Delta | $3.92M | ||
The managed scenario uses a 3.5% net trend, which is achievable under self-funding with active claims management, reference-based pricing, or direct contracting. It's not a fantasy number. It's what employers actually running their benefits like a CFO problem, not an HR task, are hitting.
Nearly $4 million in cumulative overspend over five years. That's not a rounding error. That's a capital project. That's headcount. That's margin.
Plan Design Changes Aren't Enough on Their Own
The typical response to a bad renewal is a plan design change. Raise the deductible. Shift cost to employees. Call it done. The Inclusively data is clear that even those moves only get you to 5.8–7.3% net increase. You're still running uphill.
The employers actually bending the curve are doing something structurally different. According to Mercer's 2025 benefits survey, 35% of large employers will offer a non-traditional medical plan option in 2026, specifically designed to deliver higher-quality, more cost-efficient care. That number was far lower five years ago.
One option Mercer highlights is variable copay plans. These set copayments based on individual provider fees and steer employees toward lower-cost providers without forcing a narrow network. No or low deductibles. Cost-conscious by design. 6% of large employers have already adopted them with measurable impact.
Why Mid-Market Employers Are Behind
Large employers have benefits teams, consultants, and actuaries running this math every year. Mid-market employers, your 100–500 life companies, usually have a generalist HR director and a broker who shows up at renewal. That gap in capacity is exactly why the passive renewal default persists.
But the CFO at a 300-life company has the same math problem as a Fortune 500. The trend doesn't care about headcount. The compounding doesn't slow down because you're busy. And the carrier isn't going to flag that you're overpaying.
Self-funding, combined with active stop-loss management and real claims data access, is the primary lever available to mid-market CFOs who want off the treadmill.
Mercer's data and Inclusively's projections both point the same direction. Passive management is the expensive choice, not the safe one.
The Question You Should Ask Before the Next Renewal
What's your current trend rate? Not what the carrier told you. What does your actual claims data show? If you can't answer that, you don't have a benefits strategy. You have a subscription you renew every year without reading the bill.
The 5-year model above uses conservative assumptions. An 8.5% group medical trend is the projection, not the ceiling. A bad pharmacy year, a high-cost claimant, a specialty drug you didn't budget for, and that number climbs.
Meanwhile, the managed scenario is achievable today for employers willing to change the structure, not just the copays. The cost of doing nothing isn't zero. It's $3.9 million over five years for a mid-size employer. That's the number your carrier hopes you never model.
